(D) The mRNA expression of N-cad (Exo-3B, P < 0.0001; Exo-3B-KD, P = 0.0015), Snai1 (Exo-3B, P = 0.0011; Exo-3B-KD, P = 0.0010), β-catenin (Exo-3B, P = 0.0015; Exo-3B-KD, P = 0.1158) and Vimentin (Exo-3B, P = 0.1211; Exo-3B-KD, P = 0.7113) in tumor cells, which were treated with exosomes. The gene discussed is SNAI1; the disease is neoplasm.
